BACKGROUND OF THE INVENTION

In related technologies, with the development of mobile Internet, mobile terminals have become an indispensable tool for people's work and life. Many industries such as mobile payments, instant messaging, messaging, video, online games, webcasts, VR/AR (Virtual Reality/Augmented Reality), Internet of Things (IOT) rely on mobile data services. Consumers are increasingly demanding mobile data services, but when roaming across borders, high traffic charges put more pressure on consumers.
WIFI mode is limited by the coverage of hotspots, the security of use, poor mobile usability and cost (quite a large area of WIFI is not free, and the cost is very high) and other factors, can only meet the limited user needs; and mobile networks undoubtedly have WIFI in terms of mobility, coverage, and security. The main problem with the incomparable advantages is the cost of use.
The means of reducing user fees is mainly to reduce the cost of using traffic, which is nothing more than the use of low-cost traffic from local operators distributed around the world, and then share this traffic among multiple unlimited users (including people or things in IOT), and consume how much traffic is used to achieve the purpose of reducing the cost of using traffic. In order to achieve this goal in terms of specific implementation technology, it is necessary to use virtual SIM (Subscriber Identification Module, user identification card) card, through cloud-terminal coordination and cooperation, to provide users with low-cost traffic services on a global scale. The corresponding terminal equipment came into being, and the main types of the products include MIFI (Mobile WIFI, mobile hotspot), mobile phones, built-in mobile modules for various devices (security, monitoring, on-board, logistics, etc.) and so on.
When the related technology realizes the way of virtual SIM card, there are mainly two ways, i.e., e-SIM (soft SIM) and cloud-SIM, which need to transmit relevant SIM cards and related information between the cloud and ends. The use of independent terminal equipment (mobile phone, MIFI, built-in mobile module) to achieve the function of virtual SIM card, which is required to establish two independent traffic channels between the cloud background and the mobile terminal: one is the management channel being used to transmit relevant SIM cards and related information between the cloud and ends; the other channel is the service channel, that is, the channel that users use for mobile Internet access and enjoy related content services. The main problem with the related technology solution is that the management channel is based on data services, and the traffic cost is high when roaming across borders.
For the above problems in related technologies, no effective solution has been invented.
